Physicists have finally secured direct evidence that quantum spin ice, a long-hypothesized and highly unusual state of matter, actually exists in a real material. The confirmation caps years of ...

Deep inside some magnetic materials, electrons can behave in ways that seem to defy common sense. Instead of lining up neatly like tiny compass needles, as magnets usually do, their spins remain ...

When quantum spins interact, they can produce collective behaviors that defy long-standing expectations. Researchers have now shown that the Kondo effect behaves very differently depending on spin ...

Quantum spin systems occupy a central role in understanding magnetic phenomena and phase transitions at the microscopic level. In these systems, intrinsic angular momentum (spin) interactions give ...

Researchers have experimentally recreated another fundamental theoretical model from quantum physics, which goes back to the Nobel Prize laureate Werner Heisenberg. The basis for the successful ...
